Pathological Basis of MRI Signal Changes in Multiple Sclerosis

Recruiting

• Conditions: Multiple Sclerosis

• Registration Number: NCT02659956
• Lead Sponsor: National Institute of Neurological Disorders and Stroke (NINDS)

Brief Summary

Background:

Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about MS s stages and follow them until a person s death.

Objective:

To understand how the physical and clinical signs of MS relate to its changes over time.

Eligibility:

Adults age 18 or older with MS or a disease of the brain and spinal cord that may act like MS.

Design:

Participants will have a medical history and a complete neurological exam. They may have timed tests of neurological function, such as a 25-foot walk and a 9-hole peg test.

Participants will have multi-day visits about once a year.

Participants will have blood drawn.

Participants may have a brain magnetic resonance imaging (MRI) scan. They may also have an MRI of the spinal cord. They may get a contrast agent (dye) injected into a tube in an arm vein. During the MRI, participants will lie on a table that slides in and out of a metal cylinder.

Participants will have the thickness of their retina measured using optical coherence tomography. A camera on top of a table uses lasers. Participants will look through a lens and follow instructions. Eye drops may be used to dilate the pupils.

Participants will chew on a piece of sterile cotton for 1 minute to collect saliva.

Participants agree to have an autopsy at the time of their death and to donate some of their organs to research, such as the brain and spinal cord.

Detailed Description

Objective.

The goal of this protocol is to understand how the pathology of multiple sclerosis (MS) relates to its evolution over time as observed through neuroradiological, clinical, and biological data collection in vivo.

Study population.

This study will enroll up to 200 individuals with MS, targeting 100 study completers, across various ages and stages of the disease, as well as up to 50 appropriate disease and non-neurological control participants, for a total of 250 participants.

Design.

This is a longitudinal cohort study in which participants will be seen approximately annually at the NIH Clinical Center. Most visits will extend over several days. Participants will receive ongoing care by their outside clinician. They may also concurrently participate in additional research protocols at the NIH or elsewhere, and data may be shared between those protocols and the current one. At the time of death, the central nervous system (CNS) (brain, spinal cord, retinas, and cerebrospinal fluid), as well as lymph nodes and possibly other lymphoid tissue, will be harvested.

This is a multi-site study with Johns Hopkins University. Some analysis of identifiable data will be conducted at Johns Hopkins University JHU under a reliance agreement. Patients will not be consented to the study or participate in study interventions/procedures at JHU.

Outcome measures.

Outcome measures include data derived from magnetic resonance imaging (MRI) of the brain and spinal cord, optical coherence tomography (OCT) of the retinas, clinical examination, and disability scales; radiological and pathological examination of CNS tissue; and the correlation between in vivo and postmortem measures. Particular attention will be paid to the extent to which longitudinal in vivo changes predict postmortem findings.

Primary Outcome Measures

Name	Time	Method
Correlation among in vivo imaging, postmortem imaging, and pathological characteristics of individual areas of tissue damage ("lesions") in the brain, spinal cord, and retinas.	annual visits	Correlation among in vivo imaging, postmortem imaging, and pathological characteristics of individual areas of tissue damage ( lesions ) in the brain, spinal cord, and retinas. Priority will be given to measures of myelination, axonal preservation, inflammation, and astrogliosis, as judged primarily by histological stains and immunohistochemistry.
